(Imām Bukhārī narrates): Abu Nu'aim narrated to us, he said: Zuhair narrated to us, from Abi Ishaq, he said: Hazrat Sulaiman bin Surad (may Allāh be pleased with him) narrated to me, he said: Hazrat Jubair bin Mut'im (may Allāh be pleased with him) narrated to me, he said that the Messenger of Allāh ﷺ said:
As for myself, I pour water on my head three times — he pointed to both his hands.
حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا زُهَيْرٌ، عَنْ أَبِي إِسْحَاقَ، قَالَ حَدَّثَنِي سُلَيْمَانُ بْنُ صُرَدٍ، قَالَ حَدَّثَنِي جُبَيْرُ بْنُ مُطْعِمٍ، قَالَ
قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَمَّا أَنَا فَأُفِيضُ عَلَى رَأْسِي ثَلاَثًا ". وَأَشَارَ بِيَدَيْهِ كِلْتَيْهِمَا.
